Pressure Load Fluctuation Analysis of Torque Converter Based on Fluid-structure Interaction

doi:10.3969/j.issn.1000-1093.2016.04.001

Abstract

Abstract: The load fluctuation and vibration of blade should be analyzed in the design of high power density and compact stamping-welded torque converter. The simulation is based on fluid structure interaction and dynamic mesh. The load fluctuation and vibration in time domain are extracted by setting the monitoring points along the blade from inlet to outlet. Fast Fourier transform and modal analysis are used in frequency domain analysis. The analysis results indicate that the max load fluctuation and blade vibration are at the inlet of blade because of the hydraulic impact, and the amplitudes of load fluctuation and blade vibration decay along inlet to outlet at a certain speed ratio. As the speed of turbine is higher, the amplitudes also decay. The peak frequency of load fluctuation is between the second-order and third-order modals, and also the amplitude of load fluctuation decreases at higher speed ratio.
